ANDREW PHILLIPS, OF CONEMAUGH, PENNSYLVANIA.

REVERSIBLE ROTARY STEAM-ENGINE.

Specification of Letters Patent.

Application filed December 8, 1914. Serial No. 876,121.

To all whom it may concern:

Be it known that 1, ANDREW PHILLIPS, a British subject, residing atConemaugh, 1n the county of Cambria and State of Pennsylvania, haveinvented certain new and useful Improvements in Reversible RotarySteam-Engines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will en-' ableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to steam engines, and more particularly to anengine of the reversible, rotary type.

The invention has for its object to provide a rotary motor having anovel arrangement of steam feed pipes and a valve controlllng the flowof steam through the pipes, whereby the direction of rotation of therotor may be quickly and easily reversed.

Another object is the provision of a rotary steam engine embodyinga'novel type of rotor having twin sets or series of blades separated bya partltion or wall to lncrease the power efliciency of the engine.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawings, in which,

Figure 1 represents a side elevation of the engine complete, partlybroken away, and Fig. 2 represents a sectional view on the line 22 ofFig. 1.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates the base of the engine which is supported upon a suitablefoundation 6 and on which is secured a cylinder 6 provided withremovable side walls 7 secured thereto by the bolts 8. The side walls 7of the cylinder are formed with axial openings 9 alining with thebearings 10 secured on standards 11 positioned upon the base 5, androtatably receiving the shaft 12. A rotor is keyed on the shaft 12between the side walls 7 and includes a body or hub 13, a partition 14secured circumferentially thereon and arranged centrally between aplurality of blades 15 arranged in series on opposite sides of thepartition 14. The base or inner portions 16 of the blades are concaveand secured to the hub portion 13, and the outer extremities of theblades are formed with concavo-convex heads 17, the concave faces beingarranged inwardly.

Nozzles 18 are secured in one side of the cylinder 6 and at an angle toa radial plane of the rotor to direct a spray of steam against theblades 15 to rotate the engine in one direction. The nozzles 18 areconnected by a U-shaped pipe 19, which latter communicates with a branchpipe 20 secured in one of the outlet ports of a three-way valve 21. Apair of nozzles 22 are secured in the wall of the cylinder 6 at a pointapproximately diametrically opposite the nozzles 18 and are disposed at.an angle to a radial plane of the rotor to direct a spray of steamagainst the blades 15 to rotate the engine in an opposite direction. Thenozzles 22 are connected by a U-shaped feed pipe 23, which lattercommunicates with a branch pipe 2 1 secured to the web portion thereof,and communicating with another outlet port of the valve 21. A steam feedpipe 25 is connected with the valve 21, and the latter is adapted to be0 erated by a hand lever 26 carrying a pawl 2 adapted to engage the racksegment 28 to Patented one 8, 1915;

lock the lever 26 in adjusted position. By

proper adjustment of the valve 21 the flow of steam to the pipes 19 and23 may beentirely stopped or steam may be admitted al- .ternately tosaid pipes to rotate the engine in the desired direction, as will beunderstood.

The lower portion of the cylinder 6 is formed with an openingcommunicating with an opening in the base 5 and constituting an exhaustport whereby steam is exhausted from the interior of the cylinder.

hat I claim is 1. A rotary reversible steam engine comprising a casingor cylinder, a shaft rotatably mounted in said cylinder, a rotor securedon said shaft within said cylinder including two sets of radiallydisposed blades, a partition separating the sets of blades,concavoconvex heads carried by the outer extremities of the blades,pairs of substantially diametrically opposed nozzles secured to the wallof said cylinder and disposed at an angle to a radial plane of saidrotor, steam feed pipes connected with said pairs of nozzles, and meansfor alternately admitting steam to said feed pipes.

2. A rotary reversible steam engine comprising a casing or cylinder, ashaft rotatably mounted in said cylinder, a rotor secured on said shaftwithin said cylinder including two sets of radially disposed blades, apartition separating the sets of blades, concavoarranged in the secondmentioned pipe, and convex heads carried by the outer eXtremia steamfeed pipe communicating With said ties of said blades, pairs ofsubstantially diathree-Way valve.
